Daniel 3:19-20

19Then Nebuchadnezzar was filled with rage, and the expression on his face changed toward Shadrach, Meshach, and Abednego. He gave orders to heat the furnace seven times more than was customary,

20and he commanded some of the best soldiers in his army to tie up Shadrach, Meshach, and Abednego and throw them into the furnace of blazing fire.
